Hovercraft vs. Maglev

By b-boy Fuzz

Intro

       What if you needed to get to a job interview in 10 minutes at the other side of town?  You’re car on state street can only go 45 MPH.  If we had maglev cars this wouldn’t be a problem.  You could get there in about 5 minutes.  That is enough time for you to get something to eat on the way.  In this report you will learn about what a hovercraft is, what a maglev is, the history of both, some interesting facts, and how they work.     

What is a Hovercraft?

         In this paragraph I will tell you about the Hovercraft.  The hovercraft is a secondary method of transportation using a cushion of air and some fans to push itself on smooth surfaces.  The US military and militaries all over the world use hovercrafts to carry troops and supplies across the ocean.

       In this paragraph I will answer the question, “why do we use hovercrafts?”  The answer is they are fast and efficient.  They can go up to 80 MPH with no bumps when they go. According to Wikipedia, “hovercrafts save energy and can carry more than most boats.”

What is Maglev?

In this paragraph I will tell you about maglev. Have you ever experimented with magnets?  Well if you have you know that if you get two north polarity magnets to face each other you will get a push.  You also would know that they would attract if you flip one over.  Well if you contain the two magnets that are pushing against each other (put walls on the sides of the magnets) and then balanced the weight while pulling the balanced magnet with the other magnets you will get a car going at good speeds that can turn.  That is a form of maglev.

         In this paragraph I will tell you about the different maglev trains.  According to maglev.com, in the world there are 20 different maglev trains.  The most recently made is in Dresden, Germany. The first Maglev-Conference was held 1977 in Boston, USA.   Since then they have made many different maglev trains.

 

History

       In this paragraph I will tell you about who made the hovercraft. Christopher Cockerell invented the hovercraft in 1956. The theory behind one of the most successful inventions of the 20th century, the Hovercraft, was originally tested in 1955 using an empty KiteKat cat food tin inside a coffee tin, an industrial air blower and a pair of kitchen scales. Sir Christopher Cockerell developed the first practical hovercraft designs; these led to the first hovercraft to be produced commercially, the SRN1.  This invention has changes many lives and inspired many people.

         This paragraph is about where hovercrafts were first made.   According to About.com “the first hovercraft was built in England. ”  The British people were pretty advanced probably when they made the hovercraft.

How it works

       What is EMS? According to wikipedia EMS is how the trains levitates above a steel rail with electromagnets, and on the train, repel to make the train levitate at approximately 15 millimeters.  With EMS or Electro magnetic Suspension we can go far with less energy. 

         In this paragraph I will tell you how ACV works.  ACV is short for Air Cushion Vehicle.  Many countries use these for across the sea voyages with their military.  According to wikipedia, “ACV is the most efficient way to carry things, people, and weapons across the sea and smooth surfaces.”

Interesting facts 

       In this paragraph I will tell you about how many passengers maglev trains can carry.  According to James Powell and Gordan Danby, Maglevs can carry tens of thousands of people.  The biggest maglev train The MAGLEV 2000 can carry about 200,000 people at high speeds of 631MPH. 

       Why don’t we use maglev cars?  There are three reasons why.  First they are way, way expensive.  To make one you would need to use over 9 billion dollars.  That is more money than anyone in the world has.  Second, it would have to be perfect, otherwise it would break and millions of lives would be in jeopardy.  Lastly, the tracks have really advanced technology.  I barely figured out how to but still have mistakes.    

         Can we use maglev to get things into space and planes into the air?  Yes.  If we get a maglev Chasis (the piece that makes it hover.) that can go up to 700 MPH we can get something into space.  The hard part is getting the rocket to stick to the chasis until it gets into the air.  If we grip it just right then throw the rocket, we might get it into space with 50% less fuel.

 

Conclusion

So remember how they work, what they are, interesting facts, and the history.  So you can now make it to that job interview in less time. I hope you liked my report on hovercrafts.
